Hey, such a treatise deserves the exposure. lol.
He didn't give up those interests - and Lorelai encouraged him to pursue them, to have it all.
What's more to the point is how
the show has failed to show us Logan's life outside of Rory, and for a long time, it failed to show much of Rory's life apart from Logan. This doesn't mean those lives didn't happen. But for a TV show, it loses impact when viewers don't see, experience, or hear about it.
Actually, Rory grew up in Stars Hollow and her roots include relationships with most of the town. Plus, you're forgetting Lane. And Mrs. Kim. And Mia. Etc.
When a child interacts daily with people for many years, at the very least, they have a formative influence on her.
It's regrettable that the writers haven't bothered to let Logan visit SH except when he turned to Lorelai for help.
You don't need to meet your boyfriend/girlfriend's family and friends or understand their past, but it adds a dimension of understanding.
Besides, as someone posted last night, that would be classic Gilmore Girls. Something that's in scant supply these days.
As Rory also rejected that life, after trying it a year ago.
Stars Hollow was obviously Lorelai's choice - Rory was a mere babe at the time.
But how can you say they looked after her and, in the same breath, claim they "didn't have a massive day-to-day impact on her life"?
Until age 16, Rory's entire day-to-day life was in Stars Hollow. She didn't only sleep there, she lived there, all day. She went to school there.
Responding to the rest of your treatise, oops, post

: You're right that Logan hasn't insisted he can't stand Paris. He's quite tolerant of most people. But that one scene of Paris and Logan together rocked. It's wasted chemistry (not romantic chemistry, just basic acting chemistry). It would be good to see more.
I think the problem is that we've had so few scenes where Rory is actually doing something while Logan is in the picture.
I'd agree that he doesn't hold her back. And perhaps - because their relationship still leaves me meh - I'd feel more invested in it if we did see Rory-Logan scenes that weren't merely about their relationship but bothered to show them both getting on with their lives while in that relationship.
